To investigate the effect of unilateral rotator cuff repair on the contralateral shoulder in patients with bilateral rotator cuff tears.
A clinical data of 46 patients with bilateral rotator cuff tears met the criteria between May 2016 and May 2019 was retrospectively analyzed. Of 46 patients, 23 patients underwent bilateral conservative treatment (conservation group), 23 patients underwent unilateral arthroscopic rotator cuff repair, and conservative treatment on the contralateral side (operation group). There was no significant difference in gender, age, disease duration, degree of rotator cuff tear, and comorbidities between 2 groups ( &gt;0.05). Before operation and at 6 and 12 months after operation, the degree of the rotator cuff tear was measured by MRI, and the shoulder function was evaluated by the visual analogue scale (VAS) score, University of California Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and range of motion (ROM) (forward flexion, external rotation,n the VAS score, UCLA score, and ASES score between 2 groups before operation ( &gt;0.05). The function scores in the conservation group were better than those in the operation group at 6 and 12 months after operation ( &lt;0.05). There were significant differences in the ROM of shoulder between pre- and post-operation in 2 groups ( &lt;0.05). And there was no significant difference between 2 groups at pre- and post-operation ( &gt;0.05).
For patients with bilateral rotator cuff tears, the unilateral rotator cuff repair can aggravate the rotator cuff tear of contralateral shoulder.

A retrospective analysis was performed on 6 shoulder recurrent anterior dislocation patients combined with joint laxity treated with arthroscopically capsular vertical mattress suturing between January 2017 and December 2018. There were 5 males and 1 female with an average age of 20.8 years (range, 19-24 years). The number of shoulder dislocation was 3-18 times, with an average of 9.5 times. The disease duration ranged from 2 to 60 months, with an average of 25.3 months. The preoperative Beighton score was 4-7, with an average of 5.8; the Instability Severity Index Score (ISIS) was 2-5, with an average of 3.5. There were 5 cases of simple Bankart injury and 1 case of bony Bankart injury. The range of motion of shoulder joint (including active flexion and lifting, external rotation, abduction and external rotation, and internal ratation) waroved when compared with those before operation ( &lt;0.05); there was no significant difference between at 6 months after operation and at last follow-up ( &gt;0.05).
The treatment of shoulder recurrent anterior dislocation combined with joint laxity by arthroscopically vertical matress suturing can achieve good short-term effectiveness.

Between January 2016 and December 2018, 12 patients with mixed medial injury associated with ankle fractures were treated with the fixation of the lateral malleolus by bone plates, the fixation of the anterior colliculus of medial malleolus by cannulated screws, and the repair of the deltoid ligament by suture anchors. There were 8 males and 4 females, with an average age of 42 years (range, 18-56 years). According to the Lauge-Hansen classification criteria, there were 11 cases of supination-external rotation type and 1 case of pronation-external rotation type. According to the Weber classification criteria, all cases were type B. The time from injury to operation was 3-6 days, with an average of 4.7 days. In each patient, X-ray films of anteroposterior and lateral views and mortise view of ankle were taken postoperatively. The motion range of ankle joints was ted with ankle fracture, which include anterior colliculus fracture and deep deltoid ligament injury. A better outcome can be achieved by employing the suture anchor repair method.
It is necessary to repair the deep layer of deltoid ligament in the mixed medial injuries associated with ankle fracture, which include anterior colliculus fracture and deep deltoid ligament injury. A better outcome can be achieved by employing the suture anchor repair method.To observe the short-term effectiveness of Endobutton plate in the reconstruction of Lisfranc ligament in tarsometatarsal joint injury.
Between March 2015 and July 2018, 18 patients with tarsometatarsal joint injuries were treated with Lisfranc ligament reconstruction by Endobutton plate. There were 12 males and 6 females with an average age of 32.5 years (range, 16-55 years). The causes of injury were traffic accident in 8 cases, falling from height in 3 cases, crushing by a heavy objective in 4 cases, and spraining in 3 cases. There were 10 cases of Myerson type A, 4 of type B1, 2 of type B2, 1 of type C1, and 1 of type C2. The interval between injury and operation ranged from 3 to 9 days (mean, 4.9 days). X-ray examination was performed regularly after operation to measure the distance between the first and the second metatarsal joints, and the visual analogue scale (VAS) score was used to evaluate the pain relief. At last follow-up, the reduction of tarsometatarsal joint was evaluated by measuring and
The reconstruction of Lisfranc ligament with Endobutton plate can stabilize the tarsometatarsal joint and achieve satisfactory foot function at early stage.

Six 18-month-old goats, weighing 30-35 kg, were used in this study. The experimental study was divided into two parts the preoperative planning and intraoperative bone resection. https://www.selleckchem.com/products/glafenine.html CT scans of the goats' lower extremities were firstly performed before the experiments. Then the CT scans were segmented to generate the femoral and tibial three-dimensional (3D) models in the YUANHUA-TKA system. The volumes and angles of each resection plane on the femur and tibia were planned. The bone resection was finally implemented under the assistance of the YUANHUA-TKA system. After completing all bone resections, the lower extremities of each goat were taken to have CT scans. By comparing the femoral and tibial 3D models before and after the experiments, the actual bone resection volumes and angles were calculated and compared with the preoperative values.
